Brazing Copper Tube To Stainless Steel

Bryan explains the difference between his and claytons approaches.

Brazing copper tube to stainless steel.

However a key advantage is that many dissimilar metals can be joined to stainless steels by brazing. Brazing copper to steel is actually pretty easy. Surfaces may be properly cleaned for brazing by brushing with a stainless steel wire brush or by a stiff rubbing with emery cloth or scotch brite. Clean tube end and inside surface of fitting the joint surface areas should be clean and free from oil grease or oxide contamination.

The brazing process can yield strong joints that are ductile clean and smooth. You can use any silver solder but you will need an acid based flux. If this video we show you how to do just that using 56 silver flux coated brazing alloy by solderweld. Generally welding holds stainless steel parts together best.

But will also cost more and requires the use of an acetylene or mapp gas torch to melt the brazing rod. If oil or grease is present clean with a commercial solvent. Regardless of the type of work you need done we guarantee it will be finished by the expected. Brazing copper will provide a stronger bond because of the high of silver in the brazing rod.

For over 40 years franklin brazing has been a leader in the heat treating industry. This is a plate heat exchanger as an r134 evaporator. Brazing stainless steels requires adequate planning as the alloys used to form joints must have properties compatible with the base metal. The joint will only be as strong as the silver solder itself.

How to braze stainless steel to copper. You can silver solder stainless to itself or to brass or copper to make easier connections without risk of corrosion problems. Hlq induction brazing machine manufacturer tested for high frequency induction brazing copper pipe to stainless steel pipe copper tubing to steel tube. Anyone have suggestions on what brazing alloys will work for brazing copper tubing to 304 stainless fittings.
